A house of Museion · Knowledge & Worlds

The living archive —and the worldsit builds.

Athenaeum is a local-first knowledge house where verified history compounds. The same archive powers Athenaeum Games — history you can step inside.

local-first provenance-tagged verified, not vibes
01 — THE ARCHIVE

Knowledge that compounds, not rots.

Every node carries its provenance. Fact is separated from myth before it becomes canon — so what you build on is sound. This is the method behind the worlds.

◆ Canon ledger · The Third Crusade 6 nodes

Verified, not vibes

Each node is provenance-tagged and weighed against its sources before it can become canon. No claim stands on confidence alone.

Yours, on disk

Your library lives on your machine. No surveillance, no lock-in — egress happens on your terms, a node at a time.

Nodes & links

Typed links turn notes into a navigable world — the same graph that becomes a tool, a syllabus, or a game.

02 — ATHENAEUM GAMES

History you can step inside.

The archive becomes playable worlds — researched, sourced, alive. Beautiful and true, with legend labelled as legend.

  • Set-pieces carry their sources — open any to read the record.
  • Geography, dates and figures verified before they ship.
  • Where the record is silent, legend is labelled as legend.
